I used all of them on my recent 700 build. Because I mounted the ESC and all of the electronics up front, I have to slide the lipos farther back in the frame to get the CG correct. Unfortunately, this causes the rear lipo to only be supported by about half of the battery tray. I thought making the lipos into a "stick" with strapping tape would help the rear lipo out.

My foray into 12s territory is definitely a work in progress.

Are you using the Align battery trays? The KDE v2 trays add about 23mm to the length of the tray and helps support larger/longer batteries. I also have almost all my stuff up front but have not balanced for CG yet. I plan on using smaller packs though, so We will see..

I have the V2 latch mount receiver upgrade, and Align's aluminum battery trays. Is it safe to just "click" the battery tray in place and fly, or should I also use Velcro straps on the frame like recommended for the original V1? Seems like the lipo tray isn't going anywhere when clicked in place. Then again, the lipo tray is a heavy SOB.

I use a velcro strap around the front after I click the pack in ... just for good measure.

I use velcro on the bottom to prevent sliding and 2 straps per battery to hold them in place (CHP tray - my favorite).....that being said i'm thinking about switching over to strapping tape as i recently had my first crash and the batteries actually broke the the straps and sheared (not sure on the order) the velcro resulting in them coming out the front and sustaining some damage.

Guys,
I'm looking for some good tips in this area. I know there are other threads about battery tray installation methods, but I haven't been able to find a situation like mine yet. I fly Zippy 5000 40c batteries in my 700e. I'm not sure if my issue is caused by my batteries' width or what, but I sure have a heck of a time getting them in and out of my machine. I have the stock setup with the Align velcro straps and adhesive sections attaching my batteries to the tray. Again, maybe my Zippys are abnormally wide (haven't tried any other brand yet) but there is so much binding between the velcro straps and surrounding frame when I slide the tray in and out that the straps are starting to fray where they rub the frame. Do others see this too? The in-flight performance is fine, with about 40 flights using this setup with no problems. Thanks.

Well with mine I use just Velcro... that being said I also use alot. The whole tray and bottom of battery are covered in it. As for it being a pain to install/remove battery I had the same problem and after a little inspection I saw that the adhesive from the Velcro on the tray had squeezed if you will its way out from under the Velcro and made its way into the track in the frame of the Heli... and it only got worse over time so I carefully cleaned all the gunk outta the track and trimmed 3/¹6 inch more velcro off the battery tray cleaned up the sticky residue .. and perfect slides like a dream. Just my. 02

Nope I don't use any straps it all. I slide the battery in from the back there's a stop in the front to stop the battery at the exact point for perfect c g, then I have holes drilled in the middle of the slides in the frame of the helli itself. In which I use a piece of all thread with a nut on both sides to hold the tray holding the batteries in place. It has worked perfect for me for 2 years

Well,
I voted "other" just to be contrary, for both velcro and strapping tape have their uses. But I do use something else, maybe others would be interested in this "5x stronger than velcro" tape:http://www.ebay.com/itm/ws/eBayISAPI...E:L:OC:US:1123
It's pricey, and maybe too thick if you've clearance problems. But when you click in a battery with a piece of this stuck to the mount and another to the batt it durn well stays put. (Maybe add one reg vanilla velcro strap around the battery for tradition's sake).
